Many household cleansers on the market contain lye or acid that are harsh upon the l hands and darken tile, marble and wooden surfaces, or grit that scratches the surface of the articles. I,

The object of my invention is a water soluble cleanser that is not harsh upon the hands and will effectively clean porcelain ware, enamel ware, and surfaces of tile,

marble, and wood, without injuring them.

My invention comprises a combination of compounds, of step-wise solubility in water, and that produces a certain bufier action and chemical reactions differing in total from the individual actions of the compounds.

The combination consists of borax, trisodium phosphate, sodium sesquicarbonate and sodium silicate.

The proportions of these ingredients are preferably twenty-four per cent borax, fifty per cent sodium sesquicarbonate, twenty-four per cent trisodium phosphate and two per cent sodium silicate.

These chemicals dissolve, hydrolyze, and

cleanser certain desirable bufi'er actions resuit, and the harsh effect upon the hands of so one chemical is modified by the soft efiect of another chemical, without detracting from the cleansing properties of either of them.

Borax is useful in softening water and in cleaning. It has a mild alkaline action not harsh to hands or clothing Trisodium phosphate is a water softener and cleanser of greater activity than borax, but it is harsh upon-the hands. Borax ameliorates this harshness by repressing the usual speed of ionization of trisodium phosphate. 5

Sodium sesquicarbonate does not eflioresce or deliquesce and is readil soluble in water, thus whilst dissolving irea sor'b moisture in stora e an become caked. It therefore enhances 'e keeping qualities of the combination.

However, all sodium carbonates, which arev soluble in water are hydrolized to a suflicient extent t show an alkaline reaction.

Because of this alkalinity, solutions of sodium carbonates are apt to attack aluminum. Sodium silicate protects aluminum against the action of alkaline solutions, and has also desirable detergent properties.

In use trisodium phosphate softens the water; borax tempers the solution of tri-- sodium phosphate; sodium sesquicarbonate both softens the water and tempers the solution besides loosening dirt and cleansing the objects, and sodium silicate whilst acting as a detergent protects aluminum against alkaline reactions. .It has in many cleaning operations, a small amount of abrasive action. When my cleanser is put upon a damp cloth the different rates of solution of the constituents thereof, coupled with the buffer action ensuing, afiords a cleaning action, without resort to grit or the insoluble silicious materials usually employed in abrasive actions. I

My cleanser does not leave tile and marble dark and slippery, nor does it darken wood and collect in cracks, and become rancid as doessoap.

What I claim is:

In a water soluble cleanser the combination of borax, approximately 24% sodium sesquicarbonate, approximately 50%; trisodium phosphate, approximately 24%; sodium WILMER CHARLES GANGIiOFF.
